The competition was fierce on Tuesday night for the "American Idol" finale inside the Nokia Theatre at L.A. Live – but contestants Kris Allen and Adam Lambert weren't the only two people battling it out – outside the theater Simon Cowell's ex-girlfriend was reportedly attacked.
The alleged incident occurred when Thibodeaux reportedly approached Seymour and asked if she was the "Idol" judge's girlfriend. Thibodeaux then allegedly attacked Seymour and attempted to choke her.
Thibodeaux has been booked on felony battery and is being held on $52,700 bail.
Seymour, who reportedly refused medical treatment, was escorted of the premises by three police officers.
